Apologies ahead of time, cause I'm sure this has been discussed somewhere on the boards. So I've never used the Pile of Loot before, but I have a ton of junk on preorder that I'm just gonna wait till it's all released. I have my POL status turned on, so I'm assuming that when I turn it off, once everything is available that I want to ship I turn it off, correct? Again, sorry to bring this up.

If it's on, then when something you preordered becomes available, it goes into there automatically. To ship it when you're ready, there will be a "Ship my loot now" link to press when you open your POL.
